Associated disorders

The TRIM32 gene is associated with autosomal recessive Bardet-Biedl syndrome (BBS)(MedGen UID: 395295) and limb-girdle muscular dystrophy type 2H (LGMD2H) (MedGen UID:78750). Additionally, the TRIM32 gene has preliminary evidence supporting a correlation with autosomal recessive neurodegeneration with brain iron accumulation (PMID: 26586575).

Pathogenic variants in TRIM32 cause an estimated 3% of clinical cases of autosomal recessive LGMD and an unknown percentage of Bardet-Biedl syndrome (BBS).

The TRIM32 gene encodes tripartite motif-containing protein 32, a ubiquitin ligase that is expressed in the sarcomere.

Assay and technical information

Invitae is a College of American Pathologists (CAP)-accredited and Clinical Laboratory Improvement Amendments (CLIA)-certified clinical diagnostic laboratory performing full-gene sequencing and deletion/duplication analysis using next-generation sequencing technology (NGS).

Our sequence analysis covers clinically important regions of each gene, including coding exons, +/- 10 base pairs of adjacent intronic sequence in the transcript listed below. In addition, analysis covers the select non-coding variants specifically defined in the table below. Any variants that fall outside these regions are not analyzed. Any specific limitations in the analysis of these genes are also listed in the table below.

Our analysis detects most intragenic deletions and duplications at single exon resolution. However, in rare situations, single-exon copy number events may not be analyzed due to inherent sequence properties or isolated reduction in data quality. If you are requesting the detection of a specific single-exon copy number variation, please contact Client Services before placing your order.
